VENTILATED CAR-FLOOR. v

SPECIFICATION forming part of Letters Patent N 0. 499,303, dated June 13, 1893. Application filed July 25,1892- Serial No, 441,221. (No model.)

To aZZ whom it may concern.-

Be it known that I, HARRY MUNROE MINTo, a citizen of the United States, residing at Mobile,in the county of Mobile and State of Alabama, have invented certain new and useful I do declare the following to be a full, clear, and exact description of theinvention, such as Will enable others skilled in the art to which it appertains to'make and .use the same.

My invention relates to an improvement in a ventilated car floor, and its novelty willbe fully understoodfrom the following description and claim, when taken in connection with the annexed drawings.

The objects of my invention are to provide a new and useful floor for freight cars that will enable fruit, vegetables or other perisli-- able articles to be transported safely, and is also a protection to merchandise, when loaded with any liquid substance, as leakage will pass through openings. I attain these objects by the mechanism illustrated in the accompanying drawings, in which Figure 1 is a top view showing top of venti-' lating floor. Fig. 2 isa top View of pegs. Fig. 3 is a side view. Fig. 4 is a sectional top view of Fig. 1.

Similar letters refer to similar parts throughout the several views.

In the drawings A refers to wooden pegs one inch square, which pass through scantlings D,the latter being four by four.

B is a top planking or floor of car.

0, are openings between scantlings or timbers D, and through which air flows.

E are side doors of car, which may be of any desired construction.

F is a side ventilation.

H are small end doors of cars, through which air enters and passes through cars, and out of E, F and H,ventilating car as it passes through.

Gare openings between planks of floor.

I do not confine myself to any particular sizes of timbers as the openings 0, are so arranged as to enable airlto circulate freely in the car, and under the planking O1' fl00l of car, thus creating. adra'ft, and rendering it possible to keep a freight car thoroughly ventilatcd. Where desired, the ventilating floor may be constructed in sections, thus rendering the ventilating floor portable.

In practice fruits, vegetables, or other perishable articles are placed in a freight car in the ordinary manner, except that they rest upon a ventilated floor, and are not subjected to heat as in the ordinary freight car.

A striking advantage of myinvention isits economical construction, and the ease by which the ventilated car floor can be attached to an ordinary freight car, whichv has openings in end of car.

Having described my invention and the manner in which the same is or may be carried into effect, I would say in conclusion that I do not limit myself to the precise details shown in illustration, as thesame may be changed to some extent without departing from the spirit of my invention, but

What I claim, and desire to secure by Letters Patent. is-

A ventilated car floor consisting of the separated transverse strips and the timbers upon which they are mounted, said timbers being separated from each other at the end as described and shown so as toincrease the draft of air under the car floor.

In testimony whereof I affix my signature in presence of two witnesses.

HARRY M. MINTO.
